Title: Device for making annular foam in water
Inventor: TAKAHASHI HITOSHI
IPC: B01F33/40
Filed: 1981-12-23
Abstract: PURPOSE:To provide a titled device which supplies a pressurized gas into liquid and can dissolve the gas efficiently by providing a valve means which is mounted to a diaphragm in an accumulator to be supplied with said gas and opens or closes an outlet for gas by its displacement. CONSTITUTION:A diaphragm 24 mounted in the opening 22 of an accumulator 11 consisting of stainless steel or the like is first in the position of a chain line, and a valve disc 37 inserted freely slidably onto the preceding end of a spindle 28 mounted thereto is kept energized by a coil spring 40 to close a gas outlet 18. When in this state a pressurized gas such as air is introduced into the accumulator 11, the diaphragm 24 displaces downward together with the spindle 28, and the disc 36 detaches from the outlet 18. Then the gas enters the liquid through a nozzle 19 having elasticity, and ascends while rotating by forming vortexes. The oxygen, etc. in the air are dissolved thoroughly into the liquid by the formation of such vortexes and the liquid is forcibly recycled by the ascending flow generated in the vortexes.

Title: Surface polishing grindstone and its manufacturing method
Inventor: SHIGEYAMA MASAO
IPC: B24D3/28
Filed: 1984-10-04
Abstract: PURPOSE:To prevent the loading of a surface polishing grindstone and its polishing noise resulting from the loading to perform steady polishing works over a long term by mixing special abrasive grains on which surface treatment has been carried out into ordinary abrasive grains and letting the above treated abrasive grains fall off properly during polishing work. CONSTITUTION:Treated abrasive grains on which surface treatment has been carried out with comparatively separative resin such as silicon or fluorine resin are mixed into ordinary abrasive grains at the rate of 2-8 to 100 ordinary abrasive grains by weight, and bound to them by binder. When polishing work is carried out by means of surface polishing grindstones 10, 12 produced in the above method, the treated abrasive grains fall off comparatively early and properly from the polishing surface of the surface polishing grindstone. Thus the loading on the surface of the polishing grindstone is prevented, and therefore no polishing noise occurs.

Title: Liquid crystal color display device
Inventor: KUMAKAWA KATSUHIKO
IPC: G02F1/137
Filed: 1985-09-20
Abstract: PURPOSE:To attain excellent color display by sandwiching dichroic pigment which absorbs blue light between two substrates together with liquid crystal. CONSTITUTION:Dichroic dye molecules 2 have such property that a polarized component of blue light in the long-axis direction of dye molecules is absorbed greatly and almost no polarized component in the short-axis direction of dye molecules is absorbed. When a voltage is applied between transparent electrodes 4 and 5 of this liquid crystal color display device for time-division driving, dichroic dye molecules change in array as liquid crystal molecules change in array and the molecule array of unselected and selected picture elements is simulated as shown in a figure. Consequently, blue light of unselected picture elements is absorbed greatly, but light of selected picture elements is absorbed not so much. Therefore, the transmissivity of blue light of only unselected picture elements is almost lowered and the contrast of blue is improved.

Title: Singular point detecting method by image processing
Inventor: NAKAMURA YATSUKA
IPC: G01B11/00
Filed: 1986-09-06
Abstract: PURPOSE:To detect a singular point such as a surface flaw and stain by extracting the (n)th picture element and the (n-1)th picture element on a current scanning line as the 1st and the 2nd picture elements and the (n)th picture element on the last scanning line as the 3rd picture element. CONSTITUTION:The (n)th picture element as a 1st picture element S1 and a (n-1)th picture element as a 2nd picture element S2 on the current scanning line H1 and the (n)th picture element as a 3rd picture element S3 on the last scanning line H0 are extracted to obtain picture element data corresponding to the brightness of the respective picture elements S1-S3. Therefore, if the 1st picture element S1 is a singular point such as a surface flaw, detection data corresponding to the singular point is obtained from the difference in contrast between the singular point and the 2nd picture element S2 or the 3rd picture element S3 as the peripheral part. Then, this detection data is compared with setting data for deciding whether the singular point is an object of detec tion or not, thereby detecting the objective singular point, for example, when the detection data is larger than the setting data.
